Antistatics are necessary in many applications in the plastics industry.

Many polymers, particulary polyolefines, show very high surface residues. Hence, they can easily become electrostatically charged.

This leads to optical disturbance of the final part (attraction of dust) and to very high electrostatic charges, which can cause dangerous spark discharges.

Antistatica migrate to the surface and adsorb water molecules from moisture in the air.
The resulting very thin film of moisture on the surface is capable to transport electrostatic charges, leading to reduction of the surface resistance.

The efficiency of the antistatics depends not only on the type and concentration of the active ingredient, it strongly depends on the temperature and the humidity in the environment of the final product.

Therefore the standardized measuring of the surface resistance is always done under constant conditions at 23°C and 50% humidity.

Due to different migration rates of the antistatics it is possible to offer short term antistatics (quick migration to surface) as well as long term antistatics (slow migration) or a mixture of both.

Further, it is possible to use non-migrating antistatics. These products build a conductible network within the product, which is able to transport the charges off the surface.
These products are suitable for high demands on antistatic effect for a very long period of time.

X-antistat masterbatches are „tailor made“ products, which are developed for your demands on surface resistance, type of polymer and duration of the antistatic effect.
